Abstract
A method for operating a jetting module includes applying to a drop forming mechanism a sequence of drop formation waveforms in which a small-drop waveform applied after another identical small-drop waveform causes a small drop of volume Vs to be formed; applying a large-drop waveform after another identical large-drop waveform causes a large drop of volume VL to be formed, and applying a large-drop waveform adjacent to a small-drop waveform can be done in a way that produces a large drop having a volume VL2, where VL2 is different than VL and a small drop of volume VS2, where VS2 is different than Vs.
